Rejetting 101 for the Suzuki Intruder VS1400
For your information: I mess with my bikes because otherwise life would be too "boxed" for me. You can do it too. Don't be paying those high rates unless it is something you can't do. Jetting is a science in itself but when you buy a set of pipes that comes with a jet kit and SOMEBODY HAS DONE THE WORK ALREADY FOR YOU with the proper settings. DO IT YOURSELF. I have to thank James Anderson of CruiserMagic2 for a fine product and the settings. However, I don't understand anything unless there is a picture attached to it. So I took the time to document what these people don't dare to document. No guts no glory is my motto. I hope that it is yours too. If you screw things up, then spend the money. But you know what? The mechanics around here are not very bright and they usually have a rookie mess your bike up wasting you tons of money, time and aggravation. My bike runs like a bullet now. No farts. No hesitation. I love it more than ever! I learned a lot and got a lot of satisfaction out of the learning process. Enjoy!
Settings according to cruisermagic2 go to their website for their pipes and the sound video www.cruisermagic2.com
Welcome to the chief's patient
Taking things apart. Notice the air filter already installed on the front carburetor. I will do the back one for you. Unplug the battery first.
The back carburetor pilot jet. 155 is the number for this one. 145 is the one for the front carburetor.
Unhook the fuel line attached to the carburetor and unscrew the rubber hoses front and back of the carb.
Twist the carburetor. Do not detach anything else. No need to.
Here is the infamous bronze plug of the rear carburetor. Same thing for the front.
Drill the Mother. Don't be afraid. Easy does it. Start with a smaller drill bit if you feel more comfortable. The trick is not to touch the screw underneath the bronze cap. Don't worry, there is some empty space between the two.
Twist the pilot screw 2 1/4 "full" turns out (counter-clock wise) per cruisermagic2 recommendations.
Remove the 4 screws that hold the carburetor's float. We are going to change the main jet now. The pilot jet stays stock.
Use the 155 for the rear carburetor. 145 for the front one.
Once you replace the main jet screw the bottom part of the carburetor back in. Use a low strength loc-tite on the screws.
Now unscrew the bronze looking cap where the Jet needle hides. I mark everything because my mind is in orbit all the time so I can get back to reality when convenient
J . 
Here is where the jet needle parks its ass. Unscrew the two screws. Easy. They are crap and they are loc-tighted a bit. What I do to remove them is to press as hard as I can on them and then twist slowly. Can't punch these little fuckers.
Set the ring on the third groove for the back carburetor. Set it to the fourth for the front one.
Put the needle back the way you found it. All components must be assembled in the same order.
Now put the bronze cap (the big mushroom type) on top of this. Don't forget to align the hole of the rubber thing when setting it and to insert the spring in the hole. It is a bit tricky but not that bad. Then connect the fuel line and install the K&N filter.
That is it. Install your pipes, the tank and the seat and you should be ready to go. Happy riding!
So Long, Peace, Love and prosperity to everyone
